Flash flood warnings issued to residents in burn areas

A flash flood warning was issued Friday morning by the National Weather Service for the areas of Azusa and Glendora near the potentially unstable hillsides that have been stripped of nearly 90 percent of their vegetation by last month’s Colby Fire.

The National Weather Service said they have received reports of mud and mud flows “possibly getting into homes” near Highland Drive in Glendora and Ridge View Avenue in Azusa, said Scott Sucup, meteorologist.

Alerts were sent to cell phones of those living within the Colby Fire burn area, as well as to Monrovia residents living near the hillside denuded from the Madison Fire last year, and those around the Williams Fire and the Madre Fire.

Flash flood warnings are issued when flooding is “imminent or occurring,” according to the NWS. Residents living near burn areas should move to a second story or shelter in place.

The alert, sent at 9:42 a.m., also interrupted radio and televisions programs, he said.
